I really do not understand what you are after.Off grid for the power to the server, thats no problem. Off grid to the net is impossible. You can have a wireless connection to a mast somewhere, or even to something in the space, but it is just a bit of the way, somehow you will be connected to the net, the worlds greatest grid. If you want to avoid the grid, simply put IP 127.0.0.0 and you are off grid with your server, and it is pure local. Dont forget check all parts in your computer if it is Made in Canada otherwise you forsee something.
